- Terrain Elevation | NASA Earthdata
NASA's terrain elevation data measure current height and changes in land altitude and are useful for creating digital elevation models
- What is the altitude of the International Space Station?
This altitude allows the ISS to remain in a stable orbit while still being close enough for supply missions and crew rotations The ISS travels at a speed of about 28,000 kilometers per hour
- On what date does sun appear to be at its highest altitude at . . . - Answers
The altitude of the sun is the angle between the sun and the observer's horizontal plane It changes throughout the day as the sun rises and sets At solar noon, when the sun is at its highest
- Does humidity change with altitude - Answers
Altitude is primarily based on air pressure, not temperature and humidity Additional information, such as air pressure or location, would be needed to accurately determine altitude
- Digital Elevation Terrain Model (DEM) | NASA Earthdata
A digital elevation model (DEM) is a three-dimensional graphic of the "bare earth" surface of land shown without trees, buildings or other objects
- Air Mass Density | NASA Earthdata
Dry air is referred to as air from which measurable amounts of water vapor have been physically removed Pure, dry air has a density of 1 293 kg m−3 at a temperature of 273 K and a pressure of 101 325 kPa Apart from the variability of water vapor, the composition of air is essentially constant to an altitude of at least 50 km
- SRTM | NASA Earthdata
Used to gather topographic (elevation) data of Earth's surface, NASA's SRTM used interferometry
- OpenAltimetry | NASA Earthdata
NASA’s OpenAltimetry is a free and powerful map-based data visualization and discovery tool for exploring surface elevation profiles from the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) and ICESat platform mission altimetry data
